Renewable energy does not thermodynamically warm the climate – wind and solar power do not add energy to the global heat budget
Good news: renewable energy does not warm the climate, because its impact is negligible in the global heat budget. The only way it could warm is through the carbon emissions from its construction, but also that is negligible. The main cause of global warming is fossil fuels and the use of fossil energy in transport.…
